Consume items on the map
The functions here consume accessible items / item charges on the map or in vehicles around the player (whose positions is given as origin). They return a list of copies of the consumed items (with the actually consumed charges in it). The quantity / amount parameter will be reduced by the number of items/charges removed. If all required items could be removed from the map, the quantity/amount will be 0, otherwise it will contain a positive value and the remaining items must be gathered from somewhere else.

Detailed Description

Manage and cache data about a part of the map.

Despite the name, this class isn't actually responsible for managing the map as a whole. For that function, see mapbuffer. Instead, this class loads a part of the mapbuffer into a cache, and adds certain temporary information such as lighting calculations to it.

To understand the following descriptions better, you should also read Map Management

The map coordinates always start at (0, 0) for the top-left and end at (map_width-1, map_height-1) for the bottom-right.

The actual map data is stored in submap instances. These instances are managed by mapbuffer. References to the currently active submaps are stored in map::grid: 0 1 2 3 4 5 6 7 8 In this example, the top-right submap would be at grid[2].

When the player moves between submaps, the whole map is shifted, so that if the player moves one submap to the right, (0, 0) now points to a tile one submap to the right from before

◆ add_vehicle_to_map()

std::unique_ptr< vehicle > map::add_vehicle_to_map	(	std::unique_ptr< vehicle >	veh,

private

Takes a vehicle already created with new and attempts to place it on the map, checking for collisions.

If the vehicle can't be placed, returns NULL, otherwise returns a pointer to the placed vehicle, which may not necessarily be the one passed in (if wreckage is created by fusing cars).

Parameters

veh	The vehicle to place on the map.
merge_wrecks	Whether crashed vehicles become part of each other

Returns: The vehicle that was finally placed.

Returns a pair where first is whether anything was smashed and second is if it was destroyed.

Parameters

◆ build_seen_cache()

void map::build_seen_cache	(	const tripoint &	origin,

protected

Calculates the Field Of View for the provided map from the given x, y coordinates.

Returns a lightmap for a result where the values represent a percentage of fully lit.

A value equal to or below 0 means that cell is not in the field of view, whereas a value equal to or above 1 means that cell is in the field of view.

Parameters

origin	the starting location
target_z	Z-level to draw light map on

◆ creature_on_trap()

void map::creature_on_trap	(	Creature &	critter,
		bool	may_avoid = `true`
	)

Apply trap effects to the creature, similar to creature_in_field.

If there is no trap at the creatures location, nothing is done. If the creature can avoid the trap, nothing is done as well. Otherwise the trap is triggered.

Parameters

critter	Creature that just got trapped
may_avoid	If true, the creature tries to avoid the trap (Creature::avoid_trap). If false, the trap is always triggered.

◆ draw()

void map::draw	(	const catacurses::window &	w,

Draw a visible part of the map into w.

This method uses g->u.posx()/posy() for visibility calculations, so it can not be used for anything but the player's viewport. Likewise, only g->m and maps with equivalent coordinates can be used, as other maps would have coordinate systems incompatible with g->u.posx()

Parameters

w	Window we are drawing in
center	The coordinate of the center of the viewport, this can be different from the player coordinate.

◆ function_over()

Runs a functor over given submaps over submaps in the area, getting next submap only when the current one "runs out" rather than every time.

gp in the functor is Grid (like get_submap_at_grid) coordinate of the submap, Will silently clip the area to map bounds.

Parameters

start	Starting point for function

fun	Function to run

◆ move_cost() [2/2]

int map::move_cost	(	const tripoint &	p,

Calculate the cost to move past the tile at p.

The move cost is determined by various obstacles, such as terrain, vehicles and furniture.

Note: Movement costs for players and zombies both use this function.

Returns

The return value is interpreted as follows:

Move Cost	Meaning
0	Impassable. Use `passable`/`impassable` to check for this.
n > 0	x*n turns to move past this

Place items from item group in the rectangle f - t.

Several items may be spawned on different places. Several items may spawn at once (at one place) when the item group says so (uses item_group::items_from which may return several items at once).

Parameters

loc	Current location of items to be placed
chance	Chance for more items. A chance of 100 creates 1 item all the time, otherwise it's the chance that more items will be created (place items until the random roll with that chance fails). The chance is used for the first item as well, so it may not spawn an item at all. Values <= 0 or > 100 are invalid.
p1	One corner of rectangle in which to spawn items
p2	Second corner of rectangle in which to spawn items
ongrass	If false the items won't spawn on flat terrain (grass, floor, ...).
turn	The birthday that the created items shall have.
magazine	percentage chance item will contain the default magazine
ammo	percentage chance item will be filled with default ammo

Returns: vector containing all placed items

◆ save()

void map::save ( )

Add currently loaded submaps (in grid) to the mapbuffer.

They will than be stored by that class and can be loaded from that class. This can be called several times, the mapbuffer takes care of adding the same submap several times. It should only be called after the map has been loaded. Submaps that have been loaded from the mapbuffer (and not generated) are already stored in the mapbuffer. TODO: determine if this is really needed? Submaps are already in the mapbuffer if they have been loaded from disc and the are added by map::generate, too. So when do they not appear in the mapbuffer?

◆ shift_traps()

void map::shift_traps ( const tripoint & shift )

As part of the map shifting, this shifts the trap locations stored in traplocs.

Parameters

shift The amount shifting in submap, the same as go into shift.

◆ spawn_monsters()

void map::spawn_monsters ( bool ignore_sight )

Spawn monsters from submap spawn points and from the overmap.

Parameters

ignore_sight If true, monsters may spawn in the view of the player character (useful when the whole map has been loaded instead, e.g. when starting a new game, or after teleportation or after moving vertically). If false, monsters are not spawned in view of player character.
